Title: Method of and apparatus for moving an object along a surface
IPC: B23Q5/28
Filed: 1974-04-05
Abstract: 1468890 Actuating slides LKB-PRODUKTER AB 5 April 1974 [6 April 1973] 15189/74 Heading B3B [Also in Divisions H2 and G2] An object, which carries a movable impulse member, is moved on a friction surface by applying a force to the impulse member in response to an electric signal to make the impulse member strike the object, the impulse overcoming the static friction between the object and the surface and thereby causing the object to move. The static coefficient of friction between the object and the surface is greater than the dynamic coefficient, and during the application of force to the impulse member the reaction is taken up by the object, without moving. In the arrangement of Fig. 1, an electromagnet 3 is energized to attract an armature impulse member 7 to produce an impulse to move an object 2 to the left, but in the arrangement of Fig. 2 (not shown) a corresponding electromagnet (3) attracts a corresponding armature impulse member (7) to produce movement of an object (2) to the right. In the arrangement of Fig. 3 (not shown) an impulse member (11) can be attracted selectively to either of two opposed electromagnets (12, 14) and in that of Fig. 4 (not shown) either of two electromagnets (20, 22) on an impulse member (19) may be energized to move the member (19) and hence an object (2) to the left or to the right. In the apparatus of Figs. 5(a), 5(b) (not shown), a ball armature (46) may be attracted by any of four electromagnets (31-34) to cause movement of an object (28/29) along perpendicular axes. In a piezoelectric system, Fig. 6, a piezoelectric member 49 expands to cause a member 48 to strike an object 2. The systems may be used to displace work tools, e.g. a knife in an ultramicrotome.

Title: Improvements in or relating to pouring or drop delivery vessels
IPC: B65D1/08
Filed: 1937-06-03
Abstract: 498,384. Moulding hollow ware. SCHEYER, (nÚe VON PEZACHOWICZ), S., and ARCARI, S. June 3, 1937, No. 15462. Convention date, June 3, 1936. [Class 87 (ii)] [Also in Group XVII] The invention relates to drop-delivering vessels provided with so called capillary grooves 3, Fig. 1, in the spouts 2 to produce drops and prevent drip. The Specification as open to inspection under Sect. 91 comprises also spouts in which the capillary groove is slightly curved or nearly straight. In the case of porcelain vessels, a mould, Fig. 9 (Cancelled), is used in which the groove joining portion 11 is of metal or the like. The mould is in four parts consisting of two under parts a<1>, a<2>, Fig. 1 (Cancelled), and two upper parts b<1>, b<2>, (Fig. 10 (Cancelled). The part 12 forms the widened mouth 7. To prevent subsequent changes of the groove after firing, the vessel is slowly dried after moulding and before unfired bodies are glazed, the groove is wetted with a brush and if necessary remodelled to regain shape. After glazing and firing, the glaze does not adhere owing to the previous wetting. Then thin glaze is put on the walls of the groove and firing again takes place. The process can be repeated for thick glazes. This subjectmatter does not appear in the Specification as accepted.
